摘　　要：为了分析三调数据前后村庄生态空间变化,以兰州市榆中县白家堡村庄为研究对象,基于第三次全国土地调查数据提取生态源地以及生态数据,运用当量因子法(EFM),通过数据对比分析得出榆中县白家堡村庄在三调数据前后生态系统服务价值总量(ESV)增加了113.82%。研究结果表明:(1)通过增加永久基本保护农田、林地以及草地的面积,达到了提升生态系统服务价值总量的目标;(2)生态空间的优化有助于村庄加快经济建设,改善生态环境,助力产业多元化发展,构建生态网络新格局。In order to analyze the ecological spatial changes of villages before and after three adjustment data,taking Baijiabu Village in Yuzhong County as the research object,the ecological source and ecological data were extracted based on the third national land survey data,and the equivalent factor method(EFM)was used to compare and analyze the data.It was concluded that the total ecosystem service value(ESV)of Baijiabu Village in Yuzhong increased by 113.82%before and after three adjustment data.The research results proved that:(1)By increasing the area of farmland,woodland and grassland under permanent basic protection,the total value of ecosystem services is improved;(2)The optimization of ecological space is conducive to the promotion of village economic construction,the improvement of ecological environment,the promotion of industrial diversification,and the construction of a new pattern of ecological network.
